BELT CONNECTION.

l atented Nov. 22, 1921;

Application filed December 13, 1917. Serial No. 206,882.

To all whom it may concern:

B it known that we, WILLIAM YVVENDER- rroLn and CHARLns UEBELMESSER, acitizen of the United States, and a citizen of the German Empire,respectively, residing at New York city, in the county and State of NewYork, have invented certain new and useful Improvements in BeltConnections, oi which the following is a clear, full, and. exactdescription.

Our invention relates to couplings and connections, more particularlyfor use with steel bands.

The object of the invention is to provide couplings that are simple,easily made and also adaptable to the smallest diameter pulleys.

It is a well known. fact that steel bands are better conveyors of powerthan leather and are also more eflicient, more durable and much cheaperto manufacture.

The diiiiculty heretofore experienced was that there wasno simple,reasonably cheap coupling available, and after long and many experimentswe have perfected a number of simple couplings for use on steel belts.

As shown in our drawings, our couplings can all be mounted easily, andthe peculiar construction thereof guard against breaking at the jointsof the belt.

Referring to the drawings,

Figure 1 is a cross-section through one type of coupling.

Fig. 2 is a top View of Fig. 1.

Fig. 3 is a cross-section through slightly modified constructionembodying our invention.

Fig. is a top view of Fig. 3.

As shown in Fig. 1 the steel band 1 is broken off and only two ends areshown. (I and D are the ends which are laid around the guard blocks 8and 9. Between 8 and coupling.

As shown in Fig. 3, this type 1s substantially the same as that shown inFig. 1,

with the exception 01 the center block 13 being one piece instead'of twopieces as 10 and 11.

iilany other modifications have been made and tested by us, and the mostpractical have been set forth in this application, as

giving the greatest durability against breakage of the belt-sandinsuring a most satisfactory and safe gripping surface with the pulleywith which the coupling and belt c0- operate.

iVhile we have shown and described specilic structures embodying theprinciples of our invention, we wish it to be understood that ourinvention is to be limited or restricted only in accordance with thescope oi? the attached claims and various changes in details ofconstruction will readily ap pear to those skilled in the art comingwith in the spirit and scope of our invention. What we claim as ourinvention is: 1. A. belt coupling comprising a pair of convex members, acentral block memberhaving a concave face to correspond to and" tocooperate with the convexity of the pulley, said block member alsohaving concave contour surfaces to form a snug fit with said convexmembers and adapted to receive the belt ends between the same and saidconvex members, and means for clamping said members and said belt endstogether. V

2. A belt coupling comprising a pair of convex members, a central blockmember of concave contour to form a snug fit with said convex membersand adapted to receive the belt ends between the same and said convexmembers, said central block member having a concave "face correspondingto the convexity of a pulley with which said block member cooperates,and a screw passing through said members and said belt ends to clamp thesame together.

Signed at the city, county and State of New York, this 8" day ofDecember, one thousand nine hundred and seventeen.
